Witnesses told the Los Angeles Times that the point of a flagpole had been used in the stabbing.

A cell phone video captured both sides clashing in the street.

Five KKK members, including four men and a woman, were arrested on suspicion of assault with a deadly weapon for the stabbings. Seven protesters, including six men and a woman, were arrested on suspicion of assault with force likely to cause great bodily injury.

Four of those suspects were later released after investigators looked at the video.

“It’s important to remember that the Klan’s message, as reprehensible as many of us may feel it is, it’s protected by the First Amendment, and we can’t be getting in the middle of stopping them from doing that," Sgt. Daron Wyatt, with the Anaheim Police Department, said.
